[Suppres visual couner display]

I am very new to PHP, so please forgive my lack of knowledge.

I downloaded a hit counter for from PHPJunkyard.com.  It works fine, but I would like to suppress the visual display and just rack the count in the log files.  The code is reproduced below:

// SETUP YOUR COUNTER
// Detailed information found in the readme file

// Enable referer validation? 1 = YES, 0 = NO
$check_referer = 1;
// Domains that are allowed to access this script
$referers = array ("localhost","bccentre.bc.ca");

// Get page and log file names
$page = htmlentities($_GET['page']);
$logfile = "logs/" . $page . ".log";

// If $check_referer is set to 1 and if HTTP_REFERER is set to
// a value let's check refering site
if ($check_referer == 1 && !(empty($_SERVER['HTTP_REFERER'])))
{
check_referer($_SERVER['HTTP_REFERER']);
}

// If the log file doesn't exist we start count from 1 ...
if (! @$file = fopen($logfile,"r+"))
{
$count="1";
}
// If the log file exist lets read count from it
else {
$count = @fread($file, filesize($logfile)) or $count=0;
fclose($file);
// Raise the value of $count by 1
$count++;
}

// Write the new $count in the log file
$file = fopen($logfile,"w+") or die("Can't open/write the log file, please CHMOD logs folder to 777 (rwx-rwx-rwx)!");
fputs($file, $count);
fclose($file);

// Print out Javascript code and exit
echo "document.write('$count');";
exit();

// function that will check refering URL
function check_referer($thisurl) {
global $referers;
for ($i=0;$i<count($referers);$i++)
        {
if (preg_match("/$referers[$i]/i",$thisurl)) {return true;}
}
die("Invalid referer!");
}
?>
==============================================================
I tried remarking out echo "document.write('$count');";" tih "//" but that slowed the web site to a crawl.

Thanks for nay pointers you can give me.
